Moo-Tac Pro is the strongest and fastest setting glue available on the market. Developed by us in house we use this glue daily and it's simply the very best product for attaching blocks to claws. The cartridge is a large 200ml size and the patented tip systems means no cutting and no spoiling, quick and simple to use with months of life between each use this will not fail you like other cheaper cartridges. Like all glues it's best to ensure that the glue is kept at the optimum temp, around 20C and you'll get a 20 second set and a 2 minute cure. Leave the tip on after use for an air tight seal.
